Fable mode

Activate the full Fable discipline for the rest of this session:

1. Read ~/.claude/FABLE_PLAYBOOK.md (execution discipline: reason before acting, observe-then-decide, verify every edit, communication floor, grounding protocol).
2. Read ~/.claude/FABLE_CODE.md (the Claude Code behavior layer: final-message contract, readable-over-concise, tool discipline, autonomy and honesty rules). If either file is missing, the install is broken — don't hunt for other copies. Tell the user to run fable doctor (or re-run python install.py from the fable-mode checkout), then continue with the task, applying whatever Fable discipline is already in context.
3. Adopt both as standing discipline — they govern every subsequent turn of this session, not just the next reply.
4. Confirm activation in one line ("Fable mode active — playbook and behavior layer loaded."), then continue with the user's task. Do not summarize the documents back.

If the playbook is already in this context (look for a "Fable mode active" injection from the hook), skip the reads: confirm activation in one line and apply FABLE_CODE.md from context, reading it only if absent.

Scale the heavier machinery to the task: the evidence ledger and the grounding-verifier agent are for non-trivial or hard-to-reverse work, not for typo fixes (the playbook's own calibration rules apply).
